Title: Methods and systems for modulating fuel flow for gas turbine egines
Inventor: WILLIAMS BRANDON PHILIP
IPC: F02C9/26
Filed: 2009-02-12
Abstract: A method of combustion stability control for a gas turbine engine is provided, and includes the steps of receiving by a stability controller, information regarding environmental and operating conditions. The environmental and operating conditions are assessed at the controller, and at least one fuel modulating valve 612 interfacing with the controller modulates the fuel flow to the gas turbine engine. The environmental and operating conditions are measured by at least one sensor, and operating conditions can be determined by the sensor measuring combustion pressure wave amplitude and frequency (fig 3), which is then compared to a pre-programmed amplitude threshold to determine if excessive combustion instability exists. The fuel modulation frequency at which the fuel modulation valve pulses may be equal to the frequency of combustion pressure waves that exceed the pressure amplitude threshold, but the valve pulsation frequency may be out of phase with the combustion pressure wave frequency. The method further includes the steps of determining an optimal fuel modulation frequency and amplitude to reduce combustion instability, if a likelihood of combustion instability exists, and actuating at least one fuel modulation valve to reduce potential combustion instability. Systems for modulating fuel flow are also provided.

Title: Coanda effect vehicle
Inventor: WHITCHER LEE
IPC: B64C29/00
Filed: 2009-07-06
Abstract: A Coanda vehicle comprises a canopy 1 having an upper convex surface 7 and an impeller 2, 5. Features 1, 3 are provided which define a path for fluid which passes through the impeller and curves from a relatively axial direction to a relatively radial direction, the path terminating at a position adjacent the surface 7 so that fluid flow over the surface 7 produces lift. A deflector 8 is located in the path so that fluid flows over opposite surfaces of the deflector 8, the deflector 8 being curved in the same direction as the curvature of the path. By employing the invention it becomes possible to change the velocity profile across the fluid path, thus offering a potential for improved performance. The vehicle is typically an air vehicle, but may alternatively be for use under water.

Title: Sewage treatment
Inventor: RANKIN RENVILLE STEVENS
IPC: B01D21/00
Filed: 1957-04-01
Abstract: 862,504. Gravity-separation apparatus; treating sewage. DORR-OLIVER Inc. April 1, 1957. No. 10523/57. Class 46. [Also in Group XXVIII] Clarified and aerated sewage is introduced up an annular space 5 within the fixed central column E, Fig. 4, of a final sedimentation tank A, Fig. 9, and emerges at 6 within a rotary baffle 13, whence solids move towards the tank bottom and clarified liquid towards a peripheral launder D, Fig. 9. Settled solids are urged towards the tank centre by a conventional array of scraper blades O having overlapping paths and arranged on two opposing radial rake arms. Such solids are received in a pocket of small circumferential extent, adjacent the column E and lying wholly within the path of the innermost scraper blade (not shown on Fig. 9), on each arm. Two further scraper blades of short extent and at right angles to the rake arms are attached to the centre of the rake structure. Each rake arm is further provided with a set of vertical deflector plates P, Fig. 9, one adjacent to and at the inner side of each of the blades O except the innermost (the innermost plate P not being shown in Fig. 9). Each plate P forms with its blade O a wedge-shaped region through the rear opening of which pass settled solids to be engaged by the next inner blade O Solids still in suspension but collecting in the upper part of the region are discharged together with suspending liquid by hydrostatic head up pipes R, R5, Fig. 10, and into a chamber R1, Figs. 9, 10, passing thence over an adjustable weir s into a trough S. The lower pipe R is adjustable by mechanism R2 to R4 and the rate of flow of the mixed liquid and solid into the trough S is governed by this and by the adjustment of the weir s and of the (higher) weir plate d adjacent the launder D. The mixture constitutes activated material needed for the aeration stage preceding the tank and is discharged from the tank via the trough S, ports 8 in the column E, Fig. 4, a pipe 10, and a pipe 4 (not shown). The wall parts connecting the two troughs S provide an annular channel SA, Fig. 3, and the assembly is provided with a circular aperture in its base, the edge of the aperture resting on a washer 12, Fig. 4, to permit rotation upon an annular flange 11 secured to the fixed column E. A partition 9 separates the troughs S from the space 5. The trough assembly is connected to the rake arms e.g. by the pipes R5. The sides of the troughs S extend above the tank liquid level M, Fig. 10, so that the trough structure floats in the liquid. The flow up the pipes R may be assisted by compressed air supplied by a pipe T, Fig. 9, to individual valves T1 and piping T2 to T4, Fig. 10. In Fig. 1a, (not shown), the activated mixture discharged by pipe 10 (and 4) is is passed to a splitter box, whence part is returned to the raw sewage inlet of the primary sedimentation tank and the remainder to the inlet of an aeration tank lying between the primary sedimentation tank and the final sedimentation tank A.
